Dynamic Parameters in Evaluation of Fluid Responsiveness
Czechia50 participantsStarted 2020-02-01
Plain-language summary
Intravenous infusion of fluids in patients after surgery is a very important part of treatment. However, administering too much or too little fluid can lengthen the stay in the intensive care unit or even harm the patient. Therefore, fluid therapy should be tailored to the individual needs of each patient. Several methods are available to assess which patients will likely benefit from fluid administration. However, each of these methods is useful only under certain conditions. The study aims to explore some less-known, yet promising tests which could make adequate fluid administration more precise and easier to achieve.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:

* intubated and ventilated patients
* sedation without spontaneous breathing activity
* no pulmonary pathology on X-ray after surgery
* normal systolic and diastolic function of both ventricles (left ventricular ejection fraction above 50 %, TAPSE of the right ventricle above 20 mm, FAC of the right ventricle above 30 %)
* informed consent signed before surgery
Exclusion Criteria:
* aggresive artificial ventilation (PEEP above 10 cmH2O, Pmax above 30 cm H2O)

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
